Hello Herbert Fortes. Hopefully I can help out with the information you need.
The debian pkg gthumb-data built from src:gthumb contains the convertion file: https://sources.debian.net/src/gthumb/3:3.4.3-1/data/gthumb.convert/ Among other things this file specifies the gconf2 key called "show-thumbnails" should be mapped to "org.gnome.gthumb.browse show-thumbnails" gsettings schema key. The gsettings schema for gthumb on the other hand also shipped declares that no such key exists in the schema, see: https://sources.debian.net/src/gthumb/3:3.4.3-1/data/org.gnome.gthumb.gschema.xml.in/#L48 My guess is that it has simply been removed and the convertion mapping forgotten to be upgraded when doing so... This suspicion was quickly confirmed by looking at your git history: https://anonscm.debian.org/cgit/collab-maint/gthumb.git/commit/data/org.gnome.gthumb.gschema.xml.in?id=485570d6cbd5cbc5a9026acc31ba9f108e9e998b I'd strongly suggest you simply stop shipping the (outdated/broken) gconf2 convertion file in the debian pkg since all users of old gthumb versions using gconf2 should have been uograded and converted over to gsettings long ago already. I'd also urge you to contact gthumb uostream to have them remove the convertion file (or fix it if they think there are still remaining users that need to be converted). Hope thus helps clear out the confusion. Regards, Andreas Henriksson
